Asynchronous Distributed HotLog - CDC Part II In my first installment, I talked about my task to configure CDC.

I've set up both the source and target databases as detailed in the documents.

I create a simple table:

CREATE TABLE t ( x NUMBER, y DATE );

From the target database I issue the following:

BEGIN
  dbms_cdc_publish.create_hotlog_change_source
    ( change_source_name => 'T_CHANGE',
      description => 'Test',
      source_database => 'CDC_APP' );
END;
/

and shortly thereafter receive the following error:

BEGIN
*
ERROR at line 1:
ORA-01426: numeric overflow
ORA-06512: at "SYS.DBMS_CDC_IPUBLISH", line 133
ORA-06512: at line 1
ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 226
ORA-06512: at line 2


Elapsed: 00:00:57.23

So I set up tracing and I find the following in the trace file:

  value=###
  An invalid number has been seen.Memory contents are :

The way I read that is "###" is being passed to dbms_output.get_lines where it should be expecting a number.

Again, the source database is 9.2.0.7 and the target is 10.2.0.1. I uninstalled the JVM because I thought that the wrong version of java was used to load it (not that I can find any reference to it being used). Changed my path, set up an ORACLE_HOME environment variable (yes, windows XP).

I'm hoping I just mangled the configuration of my local database. Tomorrow one of the DBAs is going to walk me through this in either our DEV or TEST environments (as it should be).

Fun...
